Halliburton has launched ExpressFiber, a single-use fibre optic cable that offers accurate, direct subsurface measurements, including cross-well communication, at a price point that enables fracture monitoring on every well pad.
Understanding and optimising well and fracture interference is a significant challenge that operators face today. ExpressFiber uses distributed acoustic sensing (DAS) to acquire a direct measurement of micro seismic, strain, and temperature unlike other cross-well monitoring techniques that provide indirect estimates.
ExpressFiber, paired with Halliburton’s intelligent fracturing and subsurface monitoring services, provides real-time actionable insights of fracture growth and well interference, allowing operators to improve completions designs and gain overall capital efficiency. It can be pumped downhole in offset wells within a couple of hours, and can be installed any time before or during the fracturing operation. ExpressFiber is designed to withstand downhole conditions for the duration of the stimulation treatment before degrading, and has no impact to subsequent fracturing operations in offset wellbores.
Michael Segura, Vice-President of Production Enhancement, commented, “When it comes to direct measurement of the subsurface, fibre is the most direct and trusted sensor of choice, but traditionally it has been expensive and complex to install. Our innovative fibre portfolio transforms fracture monitoring from an application reserved for science wells to a routine solution for regular use on more wells across your asset.”
Through a five-year agreement for North America unconventionals, ExpressFiber will be enabled by FiberLine Intervention (FLI), a wellbore surveying technique from Well-SENSE Technology Limited.
